FOLDING UMBRELLA.

To all whom, it may concern:

Be it known that I, ARTHUR A. GABRIEL- SON, a citizen of the United States,'residing at Portland, in the county of Cumberland, State of Maine, have invented certain new and useful Improvements in Folding Umbrellas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to folding umbrellas and has for an object to provide an extremely simple rib and handle and brace construction that will facilitate the umbrella being easily and quickly knocked down and then will consist of but three separate parts which may be formed into a small compact bundle for storing.

With the above object in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing illustrating this invention :Figure l is a vertical sectional view of the umbrella opened. Fig. 2 is a similar view of the umbrella closed. Figs. 3, 1 and 5 are vertical sectional views showing successive stages of knocking down the umbrella. Fig. 6 is a detail perspective view of one of the ribs with attached brace and locking rib.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a stick which is composed of a grip 11, an intermediate sec tion 12 having terminal reduced threaded stems 13 and 14 at the opposite ends, and a tip section 15, the lower stem 14 of the intermediate sect-ion threading into the grip,

and the upper stem 13 threading into the tip section. The grip carries the usual spring catch 16 for holding the umbrella closed, and the intermediate section is equipped with the usual oppositely turned spring catches 17 and 18 for holding the umbrella rigid when opened.

A plurality of ribs 19 are pivotally secured at the inner ends to a notch or crown 20 carried by the tip section of the stick,

each rib consisting of two alined sections 21 Specification of Letters Patent.

ing ends as shown at 23. The outer section of each rib is equipped near the end and on the inner side with an integral eye 24 in which a ring 25 is pivotally mounted.

A plurality of locking ribs 27 are pivotally secured at the inner ends to the inner sections 21 of the ribs as shown at 28, these locking ribs being adapted to fold outwardly along the outer sections 22 of the ribs and pass into the rings 25 carried by the outer sections, thus holding the rib sect-ions extended. Notches 29 are formed in the locking ribs to receive the rings when the latter are rocked inwardly, and secure the locking ribs in operative position. To release the locking rib, the rings are rocked outwardly whereupon the locking ribs may be disengaged from the rings and the outer sections of the ribs 20 folded inwardly upon each other with the locking ribs confined therebetween as shown in Figs. 3 to 5 inclusive.

A plurality of braces 30 are pivotally secured at the inner ends to the ferrule 31 that is slidably mounted on the stick as usual, the outer ends of the braces being pivotally secured to the locking ribs as shown at 32 near the pivots of the latter. By sliding the ferrule longitudinally upon the stick the umbrella may be opened or closed in the usual manner.

A cover of any preferred type may be stretched upon the umbrella ribs as usual, such cover being omitted in the illustration for the purpose of clearness.

As shown in Figs. 1 and 2 the umbrella is opened and closed in the usual manner with the ribs and braces assuming the usual positions. To knock down the umbrella for storing, the umbrella is first partially closed and the locking ribs freed from the umbrella ribs as shown in Fig. 3. The outer sections 22 of the ribs are then folded inwardly to lie along the braces carrying the freed locking ribs with them as shown in Fig. 4. The ferrule is then pushed out wardly until in contact with the crown, this movement extending the folded sections of the umbrella ribs with the braces and locking ribs confined therebetween, beyond the tip of the stick, as shown in Fig. 5. The grip may now be unscrewed from the intermediate section of the stick, and the intermediate section then unscrewed from the tip of the stick. The knocked down umbrella will now be in but three separate pieces which may be bound together in a compact bundle equal in length to the length of the intermediate section of the stick.

What is claimed, is

A knock-down umbrella including a stick, a plurality of ribs each comprising an inner section hinged to said stick and an outer section pivotally connected to the end of said inner section, a plurality of looking ribs each connected at the inner end to one of said inner rib sections and normally extending along the corresponding outer rib section, and serving to hold said outer and inner rib sections extended, rings hinged to said outer rib sections and normally engaged in notches formed in said locking ribs to hold said locking ribs in operative position, a ferrule on said stick, and braces hinged to said ferrule and pivoted at the outer ends to said locking ribs.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.
